Updates on amifostine also include guidance on its use for both chemotherapy and radiation-therapy toxicities. With regard to dexrazoxane, the panel made only 1 change from the previous guidelines: guidance on its use in patients receiving high-dose anthracycline therapy has been deleted because of insufficient data. However, the panel highlighted its previous and ongoing recommendation that this agent not be [...]
